IMPROVEMENT l N EMERY WHEELS.

Specification forming part of Letters Patent No.126,706, dated May 14, 1872.

Specification describing a new and useful Improvement in Emery Wheels, invented by WALTER S. J ARBOE, of the city of New York, in the county and State of New York.

This invention relates to the construction of emery wheels for grinding and polishing metals; and consists in the application of disks of leather, rubber, pasteboard, textile or felted material, or any other elastic or flexible material, to one or both sides of the emerywheel, as hereinafter more fully described.

In the drawing, Figure 1 is a side View of an emery wheel with my improvement attached. Fig. 2 is a cross-section of the wheel on the line as w.

Similar letters of reference indicate corresponding parts.

emery wheel is the greater the danger of its bursting. Thin emery wheels are very necessary in the mechanic arts, but are not used to the extent they would be, or are runat low speed, on account of the risk to life and limb.

By strengthening them with some flexible m-a- ,as before stated, and placed upon only one side of the wheel, the latter application depending upon the thickness of the wheel or the speed at which -it is made to revolve.

Having thus described my invention, I claim as new and desire to secure by Letters Patent The emery wheel A, combined with a flexible disk, B, arranged on each side, and adapted to adhere to all parts thereof, as and for the purpose described.
